Finaly took the tyres up and got them properly on the rims, they´re straight now, will see how the tubless rear holds once I start ridin :D

Had to start with the cables since I can´t get the flywheel off, so orderd a puller and a new clutch cable since the one I had is sticking like grazy and isn´t a good fit, throttle wasn´t also a bolt-on... neither is it nice but works good.

With a new chain the bikes starts to look like an actual motorcycle.

Hoping to sort out the motoplat, but still have the front engine mounts and an exhaust on the list.

Raer mudguard from a GasGas TXT, will fit with some modifications so can start with the subframe and engine mounts. New grips and a clutch cable.

Still nothing from the ignition part, but I got the puller and seems like sombody has changed the stator, because it looks like there´s been some milling done there...

Didn´t get a change to visit the garage for a long time but today started working on a new ignition system, just thoughet it easyer and cheaper then messing with the motoplat!

Got a chinese pitbike cdi ignition and hoping to get it working though it will need some pretty seriouse mods.

Gonna keep the plate and had to also modify the magneto, because it woudn´t reach the cone.28580456_1673743849335564_1329998186_o.thumb.jpg.4b1d009f125e874630e60e2abb41bb5d.jpg
 

The plate is also taking shape but now comes the biggest problem, the ignition doohickey is external and doesn´t fit the housing!

Also got a new project for summer :) It´s a Honda Dominator, so when waiting on parts or just get too frustrated I can work on that.

Got the chinese ignition working and had a feeling I should try the motoplat again before gutting up the engine, because the impulse generator woudn´t fit otherwise.

So after taking it all apart and reinstalling the original parts I discovered I hadn´t attached the green wire previuosly and well, that was the ground for the stator ....<_<
Wasn´t sure but had to give it a go and this time I made a 17mm socket fit a drill and when I got the engine spinning there was a beautiful spark!

Unbelievable how stupid I could have been, so now, I´m gonna tighty up everything, set the ignition and make the front mounts!
Even without the exhaust it would be the first time the wheels start moving on this badboy! B)

I am enjoying the trip this has been, your enthusiasm for this build is great.  :thumbup:

Thanks, I had forgotten the awesome feeling of achievement when things start moving the right way...and how much you can learn from every mistake :)
I´m loving it! :D
Today was a very work oriented day but squeezed some garage time in as well, had to clean up the place because I saw and add touring the weekend and couldn´t resist - so now I also have a Honda SLR with a gearbox problem.
One car and 4 motorcycle isn´t a good idea in s 3x6 space.
But luckily I have a tunnel there, so now there´s rome for actual work and I started with the front mount. Won´t be pretty but for version 1.0 I think they´ll do the job, some welding, a few supports and we should be golden.

I am just waiting for the first video of you riding it...  When I get a bike I strip and rebuild.  I replace what is worn or damaged and end up with an as new bike.  I couldn't do what you do.

I must admit :D what you do is much more reasonable!!! I would go the same way but since this started so long ago it would be awesome to finish and I´ve enjoyed these last months too much B)
Was away for almost half a week and today was a short one, so made the kickstarter fit and tacked the front mount, hoping to get it running the next time I´m in.

So close, but still so far :)
Buttoned up the engine mounts and got the wires routed, I´ll add some plugs and a propper wiring once everything is working.
Also made the starter button a kill switch, and made the clutch cable fit but I don´t have enough movement for propper disengagement.
The last owner made the linkage longer, so I´ll have to return it to a shorter version.
Still didn´t get it started and without the clutch I couldn´t push-start it either, can´t get enough grip on the concrete, once I get the clutch working I´ll take it on a field nearby or something like that!

Small steps after a long time.
Started on the exhaust, I´ll be basing it on a Husqvarna WR250 and hopefully make it fit.

The clutch is still a concern, even when compressing to lever on the engine it won´t fully disengage, so I´m quessing I should take it apart again and give it a proper cleaning, especially the plates between the disks.

Also tried to check the timing but the borrowed strobe didn´t work, so waiting on another friend to help me out :)

Hey guys, haven´t posted for some time.
Tried to get the MX5 out of the garage only to find out the alternator had rusted shut, so took it apart and cleaned everything but it´s still not charging so I´ve been dealing with this and some mold + rust and well, just maintenace in general because I want to have it wokring properly although last year didn´t really drive it.
But, there´s heaps of space in the garage now, though I also have to rebuild the tail on my Jawa, because we´re going on an anual oldtimers ride in the end of this month.
SOOOO, a small brake from the Beta but will be getting back to it as soon as possbile.

ALL THE SPACE!!!!

Well, this small brake turned into a year... almost :D
But, all is not lost, just been extremely busy and been dealing with all kinds of other stuff, today felt like a good time to pick up this build.
I haven´t been to the garage almost half a year, was happy to find everything in place and nothing stolen :)  Now I finaly got gas for the welder and switched out the wire, dear lord, it´s a complitly different machine now!!!
Filled the gearbox with ATF and hopefully it will start working, so as soon as I finish the exhaust I´ll try to get it running before building anything else (maybe just the subframe so I could push-start it)

Made an exhaust flange from 5mm steel and cut up the donor pipes.

Now it´s starting to look like something...

Just need to properly weld it up and make a bracket or two and deal with the muffler once the subframe is finished...

Excellent work, (thought you had been abducted !) exhaust as shown might lack bottom end power ?
